PLANT-WATEBING DEVICE.

Application filed July 1,

My invention relates to certain improvements in devices for wateringplants under the surface of the ground in order to apply moisture at apoint near, or under, the roots of the plant.

One object of the invention is to construct the device so that thehandle will be in direct alignment with the penetrating tube so thatpressure can be applied with such force as to cause the tube topenetrate the ground to the depth required.

nother object of the invention is to make the valve structure anintegral part of the handle.

In the accompanying drawings:

Fig. 1 is a side view of my improved plant watering device, showing ahand grasping the hand hold.

gig. 2 is a sectional view of the handle; an

Fig. 3 is a transverse section on the line 33, Fig. 2.

The tube 1 has a sharp point 2 at one end to penetrate the ground. Abovethe point are holes 3 through which the water escapes from the tube intothe ground. The opposite end of the tube is screw-threaded as at 4, andis screwed into the threaded opening in the projection 5 of the handle6. The handle 6 is made in a single casting and has a tubular head 7 avalve casing 8, a coupling section 9 at the rear of the hand hold, and areinforcing brace 10, which connects the lower portion of the valve withthe coupling seztion 9at the rear of the hand hold. The brace 10 is madecomparatively thin, as shown in Fig. 3.

The interior of the valve casing 8 is tapered, as shown in Fig. 2. Thistapered portior rms a seat for a tapered valve 11,

which 1S provided with a stem 12 that isbent to form a handle. A screwcap 13 is 1925. Serial No. 40,885.

mounted on a threaded rojection of the handle 6 and a sprin 14 1slocated between the screw cap and t e valve. This spring holds the valveyieldingly to its seat. The \valve has a right-angled passage 15, whichcan be brought into alignment with a port 16 communicating with thepassage 17 in the hand hold 7 of the handle.

The coupling section of the handle is threaded to receive the coupling18 of a hose 19.

On referring to Fig. 1 of the drawings, it will be seen that thetransverse center of the handhold 7 is in a direct line with the tube 1so that force can be exerted directly upon the tube to cause it topenetrate the ground \to the depth desired. The hand hold is alsoarranged at an angle in respect to the longitudinal line of the tube sothat the hand hold can be grasped in the most effective position.

By the use of the device hereinbefore described, plants can be suppliedwith water, or liquid fertilizer, at a oint below the surface of theground, and: preferably, below the main roots.

I claim:

The combination in a plant watering device, of a tube having a point atone end and perforated near the point, a handle secured to the oppositeend of the tube and having a curved hollow hand-hold arranged at anangle in respect to the longitudinal line of the tube, the transversecentre of the handhold being in direct line with the tube; a valvechamber in the forward end of the handle; a valve therein havin anoperating arm extending over the ban -hold; and a coupling section attherear end of the han'dhol arranged to be attached to a hose.
